.SH NAME

lis_esolver_get_rhistory \- Get the residual history for the specified eigenpair from the eigensolver

.SH SYNOPSIS

#include "lis.h"

\fBLIS_INT lis_esolver_get_rhistory\fR(\fBLIS_ESOLVER esolver\fR, \fBLIS_VECTOR v\fR);

.SH DESCRIPTION

Get the residual history for the specified eigenpair from the eigensolver.

.SH INPUT

.IP "\fBesolver\fR"
The eigensolver

.SH OUTPUT

.IP "\fBv\fR"
The vector

.SH EXIT STATUS

The following exit values are returned:
.IP "0"
The process is normally terminated
.IP "unspecified"
An error occurred

.SH NOTE

The vector \fIv\fR must be created in advance with the function 
\fBlis_vector_create\fR. When the vector \fIv\fR is shorter than 
the residual history, it stores the residual history in order to 
the vector \fIv\fR.
